Modesto police arrested a woman on Saturday for allegedly throwing a cup of scorching hot water at a Starbucks Barista, at the downtown H Street location.

Police report that the woman, Marci Katz, was given a free cup of hot water in a 20 oz. cup. Katz reportedly was known to employees for staying in the bathroom for extended periods, so when the barista told her to not use it for more than 10 minutes — she threw the water at the barista, burning his face and neck.

The barista was treated for first- and second-degree burns to his face and neck
at an area hospital.

The incident happened on Tuesday, but Katz was not arrested until Saturday when she returned to the store and an employee witnessed the attack and called 911. She was arrested on suspicion of mayhem and a probation violation.
